There are a few recent threads about this already and at least a couple different requests on the client uservoice (link in my sig) you can add your vote to.

First I thought it worked liked this, after 2 trips i discoved it didn't
I always put it in navigate mode now, because waze doesn't know any alternative routes for the route that I take daily to my work, so I'm trying to "learn" him, at this moment no succes, he's constantly re-routing in every directions (sometimes the route make no sense at all, luckily I've onboard GPS aswell, so I don't really use him as navigation but more for the traffic info)

So i'm wondering, does it make a difference in points if you just drive of navigate?

Waze should consider two modes. By default, it should work like this. Maybe a few more options in the settings if the user wants to override these.

* When on a route, only show the reports that are relevant to that route - no range limitation.
* When not in navigation mode, show all reports withing the range that is selected in the settings.

I like the reports because I don't always enter route information. A lot of times I just turn on Waze while I am driving, and listen for traffic in the area I am driving.

No, it does not make a difference. Just running Waze will give you the same points and help improve the map data.
